Marie's Adventure Adamantite Charm
The ALTOMYOSTR shop accessory community clears call mandatory for Jurai Castle.
Adamantite Charm is the shop accessory launch-week players keep mixing up with pregnancy artifacts. It is not Crown of Fortune Cat. Crown is a one-slot pregnancy relic that replaced Naamah Symbol in v1.0f. Adamantite Charm is a combat accessory sold at the ALTOMYOSTR training-ground shop, and community Jurai clears say you need it on Marie, Elucia, and Ran — one copy is not a party buff.
Stay on v1.0h. Patch notes never rename this charm. They still change the fights you buy it for: Killswipe and Demonology Rewrite in v1.0g, Auto-milking Config in v1.0h (Release Notes).
What it is (and is not)
| Item | Slot / source | Job |
|---|---|---|
| Adamantite Charm | Combat accessory, ALTOMYOSTR shop | Jurai Castle community clears call it mandatory |
| Crown of Fortune Cat | One pregnancy artifact slot | Extra-baby chance; bypass Heritage limits |
| Matron’s Veil / Essence of Captivation | Same artifact slot as Crown | Pregnancy passives; description fixes in v1.0e / v1.0d |
| Echoes / Nun’s Stations | Fountain + sisters in Sylva | Attack and MP recovery — complementary, not a substitute |
If your inventory only has Crown equipped and you walk into Jurai Castle, you brought the wrong tool. Swap Crown off for the fight; multiples hunting can wait until you are back in Sylva (How to Get Multiples).

Where to buy it
Community wording from the Jurai Castle Boss itch thread:
You can get this at the shop at the Altomyostr training ground.
That is the verified pin. Walk ALTOMYOSTR until the training-ground shop is reachable, then buy three charms if the shop allows one per heroine. Do not assume a single charm covers Elucia and Ran.
Gold comes from Brothel shifts and dungeon drops. Do not skip Church fertility to afford charms — fertility is a different sink (Fertility Boosts).
If the shop is empty, you are early on the ALTOMYOSTR floor chain, not missing a hidden chest. This wiki will not invent a floor number the community has not published.
Why Jurai players treat it as mandatory
The three-phase community plan on Jurai Boss is explicit:
- Phase one — Elucia Shield Bash for Confused every turn; Marie and Ran feed Momo Fruits.
- Phase two — no MP-cost attacks. Spend MP only on Marie’s Shield, Elucia’s Aegis Protection, and Ran’s Sacred Dance. Standard attacks under the shield; the charm does the work if shields stay up.
- Phase three — same defense, more offense allowed; players refuse to spoil the beat.
Without the charm, phase two looks like damage reflection: a huge Hero Strike can end the fight before the boss takes a turn. That is a loadout fail, not proof the boss is unbeatable.
Pair the charm with Echoes spent at the Sylva sisters after Nun’s Stations (Echoes). Momo Fruits paper over missing MP recovery; they do not replace either sink.
Equip rules players miss
- Three bodies, three charms. The itch edit says equip it on all three characters.
- Not an artifact. It does not consume the Crown slot, and Crown does not consume this slot.
- Not a difficulty slider. Goddess Lavia’s ground item in the opening magic circle barely moves this castle boss (Difficulty Settings).
- Not a birth replacement. Deliver in Sylva first so power-ups land, then buy the charm.
Other fights
Do not assume Belobog, Hellebore, or Volkard require Adamantite Charm. Those pages stay honest about missing data (Belobog, Hellebore, Volkard). If a later clear names this accessory on another wall, it will be added there — not copy-pasted from Jurai.
Pregnancy while you shop
Walking ALTOMYOSTR still ticks gestation. v1.0g logs Overdue. Leave for Sylva City Inn. v1.0h can disable automatic milking on sleep (Content Settings).

Adamantite Charm is a combat buy, not a fertility trinket. Purchase three, equip the Jurai trio, spend Echoes, then fight. Crown of Fortune Cat waits in the artifact slot until you are hunting multiples again.
Frequently Asked Questions
Quick answers to the most common questions.
Where do I buy Adamantite Charm?
Community clears point to the shop at the ALTOMYOSTR training ground. Buy a copy for Marie, Elucia, and Ran.
Is Adamantite Charm the same as Crown of Fortune?
No. Crown of Fortune Cat is a one-slot pregnancy artifact. Adamantite Charm is a combat accessory for Jurai Castle.
Do I only need one charm for the party?
No. The verified Jurai post says equip it on all three characters. One copy is not a raid-wide buff.
Does the charm replace Echoes or Nun's Stations?
No. Spend Echoes at the Sylva sisters after Nun's Stations, then add the charm. They stack as different sinks.
